Valdesalici, S. 2015. Nothobranchius torgashevi (Cyprinodontiformes: Nothobranchiidae), a new species of annual killifish with two male colour morphs from the Lake Eyasi basin, central Tanzania. Killi-Data Series, 2015: 17–30. Abstract: Nothobranchius torgashevi, new species, is described from a single locality, a temporary ditch associated with an unnamed affluent within the Mhwala River drainage, a tributary of the Wembere River in the Lake Eyasi basin. It is assigned to the N. ugandensis species group, members of which are defined by: colour pattern in males consisting of light blue scales with a broad, irregular, reticulated pattern on the body, vivid orange or red oblique bars on the head and dorsum, a yellow or blue anal fin, and large vivid red spots on the dorsal and anal fins; head rounded slightly concave to nearly straight dorsally; predorsal profile convex from nape to posterior extremity of dorsal fin base; cephalic squamation variable. N. torgashevi can be distinguished from other species in this assemblage by a combination of characters, including colour pattern and number of scales in the transverse and circumpeduncular series. Uniquely within the genus Nothobranchius, sympatric male colour morphs differ only by possession of white or yellow pigmentation on the distal portion of the anal fin.
